I have difficulty understanding forces involved in moving magnet and conductor problem.
When a ring conductor is at rest and an ordinary bar magnet is moving, there's electric force. I have trouble understanding how the electric force arise here. Based on my understanding of Faraday's law, there should be induced current flowing in the ring conductor. So the electric force is responsible for creating current?
Here is what I mean by electric force creating current: Consider this example where the magnetic field out the page is moving to the left towards the stationary wire loop
Faraday's law tells me that the current should be flowing clockwise. I am not sure what are forces involved here. There is no magnetic force since the loop is stationary so there's electric force somewhere and I'm not sure where it came from and its direction. According to this equation $\nabla \times \vec{E} = -\frac{\partial \vec{B}}{\partial t}$, it looks like there is electric field flowing clockwise direction like the current. So the clockwise electric field which produces electric force is responsible for creating clockwise current?
Take a look at this image from this Wikipedia article,
I understand where the magnet force is coming from in the magnet frame (one with blue coordinates). But in the conductor frame (one with primed red coordinates), I have trouble understanding where the electric force came from. I don't know the source of electric field and why it points downwards. Also, I'm not sure why the primed red coordinates is moving in +x direction (see the dotted arrow). It is supposed to move in -x direction?
